Hoxd13 Expression in Limb Stages of Three Species. a-c: Mouse forelimb Hoxd13 in ridge, bud, and paddle, respectively. a’-c’: Mouse hindlimb Hoxd13 in ridge, bud, and paddle. d-f and d’-f’: Opossum Hoxd13 in forelimb and hindlimb ridge, bud, and paddle, respectively. g-i and g’-i’: Bat Hoxd13 in forelimb and hindlimb ridge, bud, and paddle. Purple staining denotes Hoxd13 expression boundary. In bat forelimb ridge (g) the posterior limb was damaged in processing, though the area of Hoxd13 expression is intact. The inset in a is an earlier bud stage between that of ridge and image shown in b. Scale bars = 0.2 mm
